HINGE MECHANISM.

T 0 all whom t may concern.'

Be it known that I, ALoNsoN D. PERKINS, a citizen of the United, Statesof America, residing at Los Angeles, in the county ot Los Angeles, Stateof California, have invented a certain new and useful Hinge Mechanism; and i do hereby declare the following to be a tall, clear, and exactdescription ot the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

rThis invention relates to improvements in hinge mechanismnmoreparticularly to such as is adapted to be connected between the framesot' windshield sections, and it may be said to consist in the provisionot the novel features and in the novel and improved construction,arrangement and combination of the parts therein, as will be apparentfrom the description and claim.

jin object ot the invention is to provide improved hinge mechanism -torconnecting parts together' for movement with respect to each other, andwhich shall operate to 'frictionally lock the parts at any point towhich they may be moved with respect to each other.

Further objects of the invention are to provide a device of the naturespecified which is practical and serviceable, simple in construction.economical to manufacture, strong and durable in use, attractive inappearance, easy to operate, and effective in action.

Other objects and the advantages ot the invention will be apparent tothose skilled in the art, from a consideration of the followingdescription of the preferred `forms of construction in which theinvention may be embodied, taken in connection with the accompanyingdrawings, in which,

Figure 1 is a view ot hinge mechanism having the invention appliedthereto, taken on the line 1-1 of Fig. 2; Fig. 2 is a View taken on theline 2 2 of 1; Fig. 3 is a view taken on the line 3 3 of Fig. 1; Fig. 4fis a view of a modified construction for the hinge mechanism, the cheekplate being removed in order to show the interior parts; Fig. 5 is aView taken on the line 5 -5 of Fig. 4t, and Fig. 6 is a view taken onthe line 6 6 of Fig. 5.

The pivotally connected substantially annular hinge members 2 and 3 mayeach be provided with a suitable part 4 whereby Specification of LettersPatent.

they may be connected with relatively movable parts or devices to whichthe hinge mechanism is applied, and the hinge member 3 may be termed toprovide a circularl wall 5 interiorly thereof with which is adapted teengage means interposed between the members whereby they may befrictionally locked in position at any point o t their movementrelatively to each other.

Referring now more particularly to the torni ot construction shown inFigs. 1 to 3 inclusive: lVithin the member 3 is movably arranged a splitdisk which is recessed in the central portion thereof to permit ofdisposing springs at each side ot a central boss 7 on the interior ofthe member 2. As shown, the springs G may be fitted over pins 9 on theparts 10 and 11 of the split disk; the springs being adapted to pressagainst the parts 10 and 11 to have the periphery oit' said partsfrictionally engage with the wall 5. A pin 12 passing through acountersunk opening` 13 in the check 8 ot member 3 and threaded intoboss 7 ot member 2 may be employed to pivotally connect the members 2and 3, and the member 2 may be connected with the parts 10 and 11 bymeans ot projections 14 on the member 2 evtending` into recesses 15:termed in the parts 10 and 11 and adapted to engage with said partswhen said member moved. It desired, one or more reinforcing ribs 16 maybe provided to strengthen the connection of the member 2 to the part-4t.

In the form of the construction shown in Figs. d to G inclusive, themember 3 consists ot a iing 17 having the interior wall 5 adj a'- centto which is movably arranged the arcshaped parts 1S and 19 against whichpress the springs 20 which are preferably itted cn pins 21 carried bysaid parts and may be arranged on each side of the central boss 22 onthe interior ot cheek 23 of member 2 and adapted to cause the peripheryot said parts to trictionally engage with said circular wall 5.Extending between the parts 18 and 19 and disposed adjacent to thecircular wall of ring 17 are projections 24 carried by member 2 whichare adapted to engage with the parts 18 and 19 when the member 2 ismoved, as will be understood. As shown, one side of the ring` 17 mayengage with an annular shoulder 25 on member 2 and the other side ot'the ring may engage with a peripheral iiange 26 on the cheek plate 27which latter may be con- Patented Mary 2t?, 1913.

nected with the member 2 by means of a pin 2S passing through the boss22. The pin 2S may be provided with a head 29 adapted to fit in acountersink 30 in the cheek 23 of the member 2 and it may have a nut 31threaded on its end adjacent to cheek plate 27 and adapted to bearagainst the latter.

From the foregoing description of two forms of construction forembodying the invention, the mode of operation of the hinge mechanismwill be readily understood; it being apparent that either of the hingemembers 2 and 3 can be moved only by overcoming the force of frictionbetween the springpressed movable parts and the circular wall 5; and itwill be understood that any relatively movable devices that may beconnected with said hinge members are automatically frictionally lockedin position at any point of their movement by the user.

Vhile two forms of construction for embodying the invention have beenillustrated and particularly described, there are various changes andmodifications thereof that will readily occur to those skilled in theart, and the right is therefore reserved to all such changes andmodifications as do not depart from the spirit and scope of theinvention as defined in the appended claim.

I claim:

A friction-locked hinge comprising complementary hinge-members, one ofsaid menr bers having an annular interior friction surface and forming ahousing for a clutch device, segmental friction blocks disposed in saidhousing and having an arcuate outer contour to engage said frictionsurface, springs interposed between said blocks and bearing uponopposite ends thereof, and the other hinge-member having a diskshapedhead bearing against the side-periphery of the complementary member andhaving separate lugs adapted toengage said friction blocks intermediatesaid springs.

1n testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses at Los Angeles, county of LosAngeles, State of California, this 1st day of May, A. D. 1911.
